Geosynthetics in roads and pavements

 

Location  

 Unless otherwise specified, silt fence should be 

placed where it will intercept all runoff from the 

site.  Extend the fence far enough uphill to 

prevent runoff from escaping around the ends.  

When continuing the fence line with a new roll 

of fencing, install the new fence to prevent silt 

from passing between the end of the existing 

fence and the beginning of the new. 

 

Silt Fence Maintenance 

Over the time required for any given 

construction project, the control of erosion and 

sedimentation will be no better than the quality 

of the maintenance effort.  The value of careful 

and prompt attention to maintenance cannot be 

overemphasized.  Routine maintenance should 

be performed on all silt fencing.  The fence line 

should be inspected after each significant rain 

event as well as at specified intervals.  If silt 

buildup is discovered, it should be cleaned from 

the fabric either by sweeping or by hand 

shoveling.  When fabric begins deteriorating 

either because of U.V. exposure or 

vandalism/debris, it should be replaced or a new 

fence should be installed adjacent to the old.
